Stem Cell and Left Ventricular Assist Device Combination Therapy

Effects of left ventricular assist device therapy on ventricular arrhythmias.

OBJECTIVES In a retrospective study, we sought to evaluate the effect of left ventricular assist device (LVAD) therapy on ventricular tachyarrhythmias in patients with advanced congestive heart failure. BACKGROUND Despite the increasing use of LVAD as a bridge to cardiac transplantation, our knowledge regarding its effect on ventricular arrhythmias is currently limited to small series. Little...

Improvement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization

In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...

Design an Equivalent Left Ventricular Assist Device for Medical Equipment Labs

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

Ventricular arrhythmias after left ventricular assist device.

Molecular signature of recovery following combination left ventricular assist device (LVAD) support and pharmacologic therapy.

AIMS A novel combination therapy consisting of a left ventricular assist device (LVAD) combined with pharmacologic therapy including the selective beta(2)-agonist, clenbuterol, has shown promise in restoring ventricular function in patients with heart failure. The aim of this study was to identify common genes and signalling pathways whose expression was associated with reversal of heart failur...
